A white male lion from Tokyo Afterschool Summoners.

"He has the strength to put and end to squabbles, the wisdom and courage to manage a Colosseum filled with ruffians, and healing abilities to treat the wounded. Thanks to him, even though many fierce battles take place at the Colosseum in Ikebukuro, not a single death has ever occurred. He Sacred Artifact takes the form of three Chakrams and he uses them to defeat the ill-mannered."
